This video continues the series on Algebra and looks at what it means to substitute into an expression (or equation!) and how to find the value by using BIDMAS/BODMAS. There are lots of worked examples and lots of theory to help you completely understand why you are doing this.
There is also reference to Soccer and Footie!
